ABSTRACT

A cabinet and container assembly comprising an enclosed cabinet having an upper opening and a lower opening. The upper opening is equipped with a pivotal disposal door. The lower opening has a hinged door, and is dimensioned such that a wheeled container may be positioned inside and locked within the cabinet. The pivotal door can be pulled forward to an open position presenting a horizontal tray on which waste materials may be rested, with the waste materials sliding along a top chute surface of the pivotal door when it is pivoted upwardly to a closed position, the waste materials sliding rearwardly and downwardly along the chute surface and across the rear edge of the pivotal door, thereby falling downwardly into the center of the open topped container. A curved upper partition positioned within the interior of the cabinet above the pivotal door and closely adjacent the read edge thereof prevents a person from reaching inside the cabinet and accessing the container when the door is partially opened. The pivotal door provides a handgrip opening generally in the shape of an inverted triangle which may be comfortable gripped by persons of different height. The container includes a hinged and lockable lid which provides handgrip openings when the lid is opened or closed, and castered wheels for rolling the container. The containers may be positioned on a transport cart with the castered wheels engaging the frame members of the cart, or stacked in a column on their sides for transit.

BACKGROUND OF THE INVENTION

This invention relates generally to cabinets for the receipt ofdisposable waste materials, and particularly a security cabinet for thedisposal of confidential papers to be recycled used in combination witha plurality of movable containers.

In many office settings, it is necessary to provide some means for thedisposal of papers and other waste material containing informationhaving a secret or confidential nature. These papers are generallyplaced within an enclosed upright metal receptacle having a slotteddepository opening, and are collected by a security officer to beshredded or burned at the end of each business day. The waste materialsmay be collected in a large bag, and placed within a wheeled cart fortransportation to the disposal facility. Due to their bulky size and theneed for access by the collecting officer, these disposal receptaclesare generally positioned in centralized locations in an office, such asin the hallways or copy rooms. There is an increasing trend to recycleall types of paper waste materials, and services have arisen whichcollect and recycle security waste materials. However, conventionalsecurity waste disposal receptacles present several obstacles to theseservices. Besides being very heavy and immobile, these conventionalreceptacles require that the waste materials be removed and placed in anunsecured bin or cart for transport to a truck utilized by the servicefor transporting the waste to a recycling facility, or else transportedto the truck in a cumbersome closed transport container.

BRIEF SUMMARY OF THE INVENTION

It is therefore one object of this invention to design a securitydisposal cabinet and container assembly which may be supplied by asecurity recycling service and positioned unobtrusively within an officesetting adjacent to conventional drawered filing and storage cabinets.

It is yet another object of this invention to design the above cabinetand container assembly such that large stacks or loads of wide paper(such as computer printouts) can be easily discarded therein, and suchthat unauthorized persons cannot remove or peruse the waste materialsafter they have been discarded.

It is an additional object of this invention to design the above cabinetand container assembly such that persons from the security service mayeasily remove the filled containers from the cabinet, replace thosecontainers with empty containers, and easily transport the filledcontainers to a truck or other remote facility. It is a related objectof this invention to design the above cabinet and container assemblysuch that the filled containers removed from the cabinet may be securedin a closed position to further prevent removal or perusal of the wastematerials during transit.

Briefly described, the cabinet and container assembly of this inventioncomprises an enclosed cabinet having an upper opening and a loweropening. The upper opening is equipped with a pivotal disposal door. Thelower opening has a hinged door, and is dimensioned such that a wheeledcontainer may be positioned inside and locked within the cabinet. Thepivotal door can be pulled forward to an open position presenting ahorizontal tray on which waste materials may be rested, with the wastematerials sliding along a top chute surface of the pivotal door when itsis pivoted upwardly to a closed position, the waste materials slidingrearwardly and downwardly along the chute surface and across the rearedge of the pivotal door, thereby falling downwardly into the center ofthe open topped container. A curved upper partition positioned withinthe interior of the cabinet above the pivotal door and closely adjacentthe rear edge thereof prevents a person from reaching inside the cabinetand accessing the container when the door is partially opened. Thepivotal door provides an handgrip opening generally in the shape of aninverted triangle which may be comfortable gripped by persons ofdifferent heights. The container includes a hinged and lockable lidwhich provides handgrip openings when the lid is open or closed, andcastered wheels for rolling the container. The containers may bepositioned on a transport cart with the castered wheels engaging theframe members of the cart, or stacked in a column on their sides fortransit.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The security disposal cabinet and container assembly of this inventionis shown in FIGS. 1--13 and referenced generally therein by the numeral10.

Referring particularly to FIGS. 1, 2 and 4, it may be seen that thesecurity disposal cabinet and container assembly 10 includes a generallyparallelepiped outer chassis or cabinet portion 11 having a pair ofopposing left and right side walls 12, a front wall 14, a rear wall 16,a top wall 18, and a generally open bottom 20 defined by the respectivebottom edges of the left and right side walls 12, front wall 14, andrear wall 16. The left and right side walls 12, front wall 14, rear wall16, and top wall 18 may be constructed from panels of cut and foldedsheet metal, or other conventional materials suitable to the locationand application of the security disposal cabinet and container assembly10.

The front wall 14 defines a small, generally rectangular first or upperopening 22 and a larger, generally rectangular second or lower opening24. Each of the upper opening 22 and lower opening 24 have a widthslightly less than the width of the front wall 14 measured between theopposing side walls 12, and each has a height, the combined heights ofthe upper opening 22 and lower opening 24 being slightly less than theheight of the front wall 14 measured between the bottom thereof and thetop wall 18.

Extending between the left and right side walls 12 at the bottom frontends thereof, and disposed beneath the lower opening 24, is a raisedthreshold channel 26 having a pair of angled or beveled sections facingupwardly and toward the front and rear. The top portion of the frontwall 14 and the left an right side walls 12 define a rearwardly beveledor angled segment 28.

Extending between the threshold channel 26 and the top and side edges ofthe lower opening 24 is a generally rectangular lower cabinet door 30hingedly connected along one of the opposing side edges thereof to pivotbetween a closed position as shown in FIG. 2 and an open position asshown in FIG. 5.

Disposed in covering relation to the upper opening 22 is a pivotal door32 which may be moved between a closed position as shown in FIG. 1, andin phantom in FIG. 4, and an open position as shown in FIGS. 3 and 4.The pivotal door 32 includes a front section 34 and a rear section 36.The front section 34 is oriented in a generally upright directionobstructing the first opening 22 when the pivotal door 32 is in theclosed position, and in a generally horizontal direction extendingforwardly from the front wall 14 when the pivotal door 32 is in the openposition. The rear section 36 is oriented in a generally downwarddirection at an approximately 45° angle and extends rearwardly from thefront wall 14 into the interior of the cabinet portion 11 when thepivotal door 32 is in the closed position, and is oriented in agenerally upwardly angled direction when the pivotal door 32 is in thecompletely open position thereby at least partially obstructing theupper opening 22.

The front section 34 and rear section 36 of the pivotal door 32 areconnected to one another at a common vertex to form a generally obtuseangle of approximately 135° relative to a normal horizontal plane. Thepivotal door 32 is pivotally mounted to the opposing sides of the upperopening 22 in the front wall 14, or alternately to the opposing left andright side walls 12, on a common axle or pair of axle members 38positioned at or closely proximate to the common vertex of the frontsection 34 and rear section 36, and defining a longitudinal axis ofrotation around which the pivotal door 32 may be pivoted or rotated.

The pivotal door 32 further has a pair of spaced-apart raised side edges40 disposed on opposite sides of the pivotal door 32 and extendingupwardly from the front section 34 and rear section 36 generallyperpendicular thereto, the raised side edges 40 extending substantiallyfrom the front to the back edges thereof and being joined along agenerally curved center section. Attached to the top surfaces of thefront section 34 and rear section 36, and extending between the raisedside edges 40 and front to the back edges thereof, is a generally smoothcovering providing a chute surface 42 fabricated from a slippery orfriction reducing plastic or Teflon sheet material.

The front section 34 of the pivotal door 32 further defines a generallyinverted isosceles triangular handgrip opening 44 having a generallystraight, horizontal top edge and a pair of upwardly facing, convexlycurved, inclined side edges, the bottom side edges being joined at thecentral ends thereof to form a downwardly pointing arrow.

Referring particularly to FIGS. 3 and 4, it may be seen that disposedwithin the interior of the cabinet portion of the cabinet and containerassembly 10 is an generally curved upper partition 46. The upperpartition 46 is fabricated from a generally rectangular panel folded asdescribed, the upper partition 46 having a front flange member 48extending along the front end thereof connected and attached to theunderside or interior surface of the top wall 18, and further having bya similar rear flange member 50 at the opposing rear end of thepartition 46 which is connected or attached to the back wall 16. Thepartition 46 includes an inwardly and downwardly angled rear section 52extending between and joining the top edge of the rear flange member 50and the bottom rear edge of an upwardly convex curved or arcuate centralsection 54. The arcuate central section 54 has a radius greater than thelength of the rear section 36 of the pivotal door 32 measured betweenthe rear edge of the rear section 36 and the longitudinal axis of theaxle members 38, the arcuate central section 54 being angled or orientedat an attitude such that the top of the arcuate central section isclosely adjacent to the rear edge of the rear section 36 when thepivotal door 32 is in the open position, but such that the angled rearsection 52 spaces the bottom rear edge of the arcuate central section 54a predetermined distance from the rear wall 16 (and a predeterminedheight or distance from the floor or other planar surface S upon whichthe cabinet portion 11 rests) so that there is sufficient clearancebetween the rear edge of the rear section 36 of the pivotal door 32 andthe bottom of the arcuate central section 54 when the pivotal door 32 isin the closed position.

Extending downwardly and forwardly from the top front edge of thearcuate central section 54 of the upper partition 46 is a rearwardlyfacing stop section 54 angled generally parallel with the top edge ofthe raised side edges 40 of the pivotal door, the upper partition 46extending at an equal but opposite angle upwardly from the front edge ofthe stop section 56 to the lower edge of a generally vertical frontsection 58, the vertical front section 58 being connected to andadjoining the front flange member 48.

When in the fully or completely open position, the forward facing topsurfaces of the raised side edges 40 of the rear section 36 of thepivotal door 32 contact the rear facing angled surface of the stopsection 56 of the upper partition 46, such that the stop section 56prevents the pivotal door 3 from being rotated or pivoted fartherforward or open, and such that the front section 34 will be maintainedin a generally horizontal position. Similarly, when in the fully orcompletely closed position, the rearward facing top surfaces of theraised side edges 40 of the front section 34 of the pivotal door 32contact the forward facing surface of the vertical front section 58 ofthe upper partition 46. The front section 34 and rear section 36 of thepivotal door 32 are each approximately equally weighted such that thepivotal door 32 is balanced across the axle members 38 and will remainin the respective open or closed position. When in the closed position,a strip or plurality of cushioning pads 60 may be disposed between andattached to either the top surfaces of the raised side edges 40 of thefront section 34 or the rear facing angled surface of the stop section56 of the upper partition 46.

Referring to FIGS. 4--7, it may be seen that a movable container 62 maybe selectively and removably received within the interior region of thecabinet portion 11 of the security disposal cabinet and containerassembly 10 beneath the upper 25 partition 46 and the rear section 36 ofthe pivotal door 32, and positioned resting upon the planar surface S. Aplurality of like movable containers 62 may be used in cooperation withone or more of the cabinets 11.

Referring to FIGS. 4 and 6--7, it may be seen that the movable container62 includes a generally rectangular front panel 64, generallyrectangular rear panel 66, a pair of generally rectangular opposing sidepanels 68, and a generally square bottom panel 70 fabricated from a thinbut resilient metal sheet material joined along the respective edgesthereof and defining a generally rectangular open top receptacle region.

The movable container 62 is dimensioned such that it may be receivedthrough the lower opening 24 when the lower door 30 is in the openposition, and further such that the bottom of the arcuate section 54 ofthe upper partition 46 is disposed generally above and closely proximateto the top edge of said rear panel 66 of the movable container 62 whenthe movable container 62 is positioned within the interior region of theouter cabinet 11.

Attached to the outer planar surface of each of the front and rearpanels 64, 66 are front and rear lid securing brackets 72, each lidsecuring bracket 72 having a generally vertical leg member 74 fixedlyattached to the corresponding front or rear panel 64, 66 and anoutwardly extending angled flange member 76 connected to the top edge ofthe corresponding vertical leg member 74. The bottom rear distal edge ofthe rear flange member 76 defines a longitudinal aperture within which ahinge rod 78 is slidably received. A container lid 80 is pivotallymounted on the hinge rod 78 to pivot between a completely closedposition disposed above and in covering relation to the receptacleregion of the movable container 62, and upwardly and rearwardly to acompletely open position whereat the container lid 80 is disposedclosely adjacent to and generally parallel with the rear panel 66 of themovable container 62.

Referring particularly to FIGS. 4, 6, and 7, the container lid 80 isfolded from a generally planar sheet material of the same type fromwhich the panels 64, 66, 68, and 70 are fabricated, and includes a reardepending segment 82, a generally square planar center lid section 84extending from the rear depending segment 82, and a front dependingsegment 86 extending from the center lid section 84. The rear edge ofthe rear depending segment 82 defines a second longitudinal aperturewithin which the hinge rod 78 is slidably received, the portion of therear depending segment 82 defining the longitudinal aperture overlappingand being aligned and cooperatingly mating with the portion of thebottom rear distal edge of the rear flange member 76.

The front and rear depending segments 82, 86 each form a generallyobtuse angle with the center lid section 84, the associated obtuse anglebeing generally equal to the angle between the vertical leg member 74and angled flange member 76 of the respective front or rear lid securingbrackets 72. As such, when the container lid 80 is pivoted to thecompletely closed position as shown in FIG. 6, the lower surface of thefront depending segment 82 will be disposed parallel to and in closelyadjacent abutting contact with the top surface of the front lid securingbracket 72, and the rear depending segment 86 will be disposed parallelto and in closely adjacent abutting contact with the top surface of therear lid securing bracket 72, with the generally square planar centerlid section 84 disposed above and covering the receptacle region. Whenthe center lid section 84 is disposed above the receptacle region in thecompletely closed position, the edges of the center lid section 84 arepreferably disposed above and in covering and contacting relation to thetop edges of the front panel 64, rear panel 66, and side panels 68.

Referring to FIG. 7, it may be seen that the bottom edge of the reardepending segment 86 of the container lid 80 defines a handgrip opening88 which permits a user access to the rear lid securing bracket 72 suchthat the front and rear lid securing brackets 72 may be used to grip andlift the movable container 62 when the container lid 80 is in either thecompletely open or completely closed position.

Referring to FIGS. 11--13, it may be seen that the opposing side walls68 of each of the like movable containers 62 defines a plurality oftruncated conical or radial bulges 90 and corresponding recesses ordetents 92, the bulges 90 being positioned and arrayed on one of theleft or right side wall 68 with the detents 92 being similarly arrayedon the opposing right or left side wall 68 such that several likemovable containers 62 may be stacked in a vertical column on their sideswith the bulges 90 being at least partially received within thecorresponding detents 92 to maintain the movable containers 62 securelystacked in the column as shown in FIG. 11.

Referring to FIGS. 4 and 6, it may be seen that a plurality of casteredwheels 94 are attached to the outer planar surface of the bottom panel70, the castered wheels 94 being spaced apart so as to support themovable container 62 in a stable upright orientation when the movablecontainer 62 is filled and is wheeled or transported on the casteredwheels 94. Referring to FIGS. 8--10, it may be seen that a plurality ofthe movable containers 62 may be transported on a cart 96 having a pairof opposing upright handle segments 98, a pair of spaced-apart framemembers 100 telescopingly connected and extending between the uprighthandle members 98, and a pair of major wheels 102 and minor wheels 104.The major wheels 102 are disposed on opposing sides of the cart 96 andare carried on a common axle 106 centered along the length of andtraversing the width of the frame members 100 of the cart 96, while theminor wheels 104 are disposed on opposing ends of the cart 96 and areindividually castered and mounted to cross members 108 extending betweenthe spaced-apart frame members 100.

Referring particularly to FIGS. 9 and 10, it may be seen that thecastered wheels 94 of each of the movable containers 62 may bepositioned on the bottom panel 70 thereof such that when the movablecontainers 62 are positioned on the top surfaces of the frame members100 of the cart 96 the castered wheels 94 may be disposed eitherstraddling the outer sides of the frame members 100 as shown in FIG. 9,or paired opposing one another alternatingly on the inside and outsideof the frame members 100 as shown in FIG. 10.

Referring to FIG. 13, it may be seen that the movable containers 62 mayinclude a security bracket or flange 110 defining an aperture throughwhich a chain or cable 112 may be inserted, and the movable container 62secured with the cable 112 and a padlock 114 to a fixed object 116 suchas a railing or other physical structure at a predetermined location ina building.

The angled flange member 76 of the front lid securing bracket 72 and thefront depending segment 86 of the container lid 80 each define acorresponding and aligned circular locking aperture 118 through whichthe shank of a padlock 114 may be passed in order to secure thecontainer lid 80 in the completely closed position when the lowersurface of the front depending segment 82 is disposed parallel to and inclosely adjacent abutting contact with the top surface of the front lidsecuring bracket 72.

Referring to FIGS. 3 and 5, it may be seen that the lower cabinet door30 includes a keyed lock 120 disposed proximate to the edge thereof, thelock 120 having a rotating tang 122 which may be received behind orwithin a slot or bracket defined by edge of the front wall 14 oradjacent side wall 12 to lock the lower cabinet door 30 in a closedposition covering and blocking the lower opening 24.

Referring particularly to FIGS. 4 and 5, it may be seen that the lowercabinet door 30 defines a recessed interior surface on which may bemounted one or more utility trays 124, the utility trays 124 being sizedand positioned so as to be received beneath the rear section 36 of thepivotal door 32 in either the open or closed position, and above theeopen top receptacle region and front wall 64 of the movable container62. The utility trays 124 are preferably sized to receive a box of bags(not shown) which may be used as replacement liners for the movablecontainer 62 and to hold a padlock 114 used to secure the container lid80 in the closed position on the movable container 62 when the movablecontainer 62 is removed from the security disposal cabinet 10.

The security disposal cabinet and container assembly 10 has an overallheight, width, and depth permitting it to be placed between or adjacentto conventional drawered filing cabinets 126, as shown in FIG. 1.

In operation, the security disposal cabinet and container assembly 10 isplaced in a convenient location either alone or in a bank ofconventional drawered filing cabinets 126. The lower cabinet door 30 isopened exposing the interior of the security disposal cabinet 10. Thecontainer lid 80 of a disposal container 62 is pivoted to the completelyopen position, a liner bag (not shown) is removed from one of theutility trays 124 and placed in the receptacle region of the movablecontainer 62, and the movable container 62 is wheeled through the loweropening 24 and over the threshold channel 26 into the interior of thecabinet portion 11 of the security disposal cabinet and containerassembly 10 with the container lid 80 disposed adjacent to the rear wall16 of the security disposal cabinet 10. The padlock 114 is placed in theutility tray 124 on the lower cabinet door 30, and the lower cabinetdoor 30 is pivoted to the closed position and secured using the keyedlock 120.

A person desiring to dispose of a load or stack of waste paper 128 mayopen the pivotal door 32 by grasping the front section 34 of the pivotaldoor 32 through the handgrip opening 44, with the palm and fingers of ataller person facing upward such that their fingers grip or contact thestraight top edge of the handgrip opening 44, and such that the palm andfingers of a shorter person will grip or contact one of the upwardlyfacing, convexly curved bottom side edges of the handgrip opening 44.

The person may then pull forwardly and downwardly on the front section34 of the pivotal door 32 such that the pivotal door 32 pivots on theaxle members 38, lowering the front section 34 and raising the rearsection 36 thereof until the top surface of the raised side edges 40contact the rear face of the stop section 56 of the upper partition 46,and the front section 34 of the pivotal door 32 is oriented in thecompletely open and generally horizontal waste material receivingposition shown in FIG. 3. The stack of waste paper 128 may then beplaced on the upper surface of the chute surface 42 of the pivotal door32 between the raised side edges 40 thereof, and the front section 34 ofthe pivotal door 32 may be lifted and pivoted upwardly and rearwardlyuntil the top surfaces of the raised side edges 40 contact the verticalfront section 58 of the upper partition 46. As the front section 34 israised, the chute surface will approach a critical angle relative tohorizontal at which gravity will overcome the friction between thebottom of the stack of waste paper 128 and the chute surface 42, and thestack of waste paper 128 will slide along the chute surface 42 acrossthe front section 34 and rear section 36 of the pivotal door 32 acrossthe rear edge thereof, and fall downwardly into the center of thereceptacle region of the movable container 62. While the rear edge ofthe rear section 36 of the pivotal door 32 will be disposed above theapproximate center of the open top receptacle region, the upperpartition 46 and rear panel 66 of the movable container 62 will therebyassist or aim the load of waste materials 128 into the open topreceptacle region of the movable container 62 as the load of wastematerials 128 slides rearwardly along and falls from the pivotal door32, and not permit the load of waste materials 128 from falling or beingcaught behind the movable container 62 due to its rearward momentum.

At this point, the pivotal door 32 may be reopened and more waste paper128 disposed using the pivotal door 32, however the close proximity ofthe arcuate section 54 of the upper partition 46 to the rear edge of therear section 36 of the pivotal door 32 prevents a person from reachinginto the lower interior region of the cabinet portion 11 of the securitydisposal cabinet and container assembly 10 and removing waste paper 128or materials from the movable container 62.

Once filled with waste paper 128, the movable container 62 may beremoved from the interior of the cabinet 11 by unlocking the lowercabinet door 30 and wheeling the movable container 62 over the thresholdchannel 26. The container lid 80 may be pivoted upwardly and forwardlyfrom its position against the rear panel 66 of the movable container 62,and downwardly into a covering position disposed over the open top ofthe receptacle region such that the edges of the center lid section 84cover the top edges of the front panel 64, rear panel 66, and sidepanels 68 of the movable container 62. The container lid 80 may belocked in the closed position by passing the shank of a padlock 114through the locking apertures 118 of the front lid securing bracket 72and the front depending segment 86 of the container lid 80 and closingthe padlock 114.

An empty movable container 62 can then be placed inside the cabinet II,with a replacement padlock being placed in one of the utility trays 124on the inside of the lower cabinet door 30, and if desired a bag may beremoved from one of the utility trays 124 and placed inside the emptymovable container 62.

The filled movable container 62 may then be placed at a predeterminedlocation for later collection, being locked to a fixed object orstructure 116 during the intervening period as shown in FIG. 13, or maybe immediately transported to a loading dock, truck, or on-site disposalfacility.

To transport one or more of the movable containers 62 to a predeterminedlocation, the movable containers 62 may be placed on the wheeled cart 96with the castered wheels 94 of the movable container 62 engaged in astraddled or alternating position relative to the frame members 100 ofthe cart 96, as shown in FIGS. 9 and 10 respectively, and the cart 96may then be wheeled to a location such as a loading dock or disposalfacility.

The movable containers 62 may then be emptied into on-site wastedisposal mechanism or loaded on a truck or other vehicle (not shown) tobe emptied at a remote location. In order to empty each movablecontainer 62, the container lids 80 may be opened, and the bags of wastepaper 128 removed. Alternately, the movable containers 62 may beindividually lifted and inverted by a person grasping the underside ofthe extending angled flange member 76 of each of the front and rear lidsecuring brackets 72, the angled flange member 76 of the rear lidsecuring brackets 72 being accessed by the person inserting theirfingers palm up through the handgrip opening 88 defined by the bottomedge of the rear depending segment 86 of the container lid 80 when thecontainer lid 80 is in the completely open position as shown in FIG. 7.

If a plurality of the movable containers 62 are to be transported in avehicle to a remote disposal or processing facility, the movablecontainers 62 may be stacked one on top of another in a generallyvertical column on their sides with the bulges 90 on the side panels 68of one movable container 62 aligned with and engaging the recesses ordetents 92 of the movable container 62 disposed above or below, as shownin FIGS. 11 and 12, to prevent the like movable containers 62 fromshifting or sliding relative to one another.
